What are apocrine glands?
A type of gland that is found in the skin, breast, eyelid, and ear. Apocrine glands in the breast secrete fat droplets into breast milk and those in the ear help form earwax. Apocrine glands in the skin and eyelid are sweat glands.
What is the difference between eccrine and apocrine sweat glands?
Eccrine glands occur over most of your body and open directly onto the surface of your skin. Apocrine glands open into the hair follicle, leading to the surface of the skin. Apocrine glands develop in areas abundant in hair follicles, such as on your scalp, armpits and groin.
What is an example of apocrine gland?
Examples of apocrine gland include the mammary glands and the axillary sweat glands. Compare: merocrine gland.
How are apocrine glands classified?
Apocrine (/ˈæpəkrɪn/) is a term used to classify exocrine glands in the study of histology. Cells which are classified as apocrine bud their secretions off through the plasma membrane producing extracellular membrane-bound vesicles. The apical portion of the secretory cell of the gland pinches off and enters the lumen.
What does apocrine gland look like?
The secretory portion of an apocrine gland is a coiled, nonbranching tube lined by a layer of cuboidal to columnar epithelial cells with round nuclei and brightly eosinophilic cytoplasm, surrounded by a layer of myoepithelial cells. The apocrine ducts per se are morphologically indistinguishable from eccrine ducts.
What are some examples of apocrine glands?
Thus, the apocrine gland differs from the other exocrine glands (i.e. holocrine andmerocrine glands) by including some parts of the cell with the secretory products. Examples of apocrine gland include the mammary glands and the axillary sweat glands.
Where in the body would you find apocrine glands?
Our apocrine glands are usually found in our armpits, our genitals, ears, breasts , and anywhere we produce hair, and become very active at the onset of puberty. These glands secrete a thicker fatty substance that when exposed to bacteria naturally found on our skin, provides a rich environment for the bacteria.
What is true regarding apocrine sweat glands?
apocrine sweat gland. n. Any of numerous sweat glands found primarily in the skin of the armpit, pubic region, and areolae of the breasts that produce a secretion that is more viscous than that formed by the eccrine glands. Secretions from these glands occur most frequently during periods of emotional stress or sexual excitement.
Where are the apocrine glands most abundant?
Apocrine Glands most abundant in axillary and genital regions; sweat ducts open into the hair follicles and become active at puberty. Secretion: increase during stress and pain, little influence on thermoregulation.
